About Ciphers

A cipher is a cryptographic algorithm used for
encryption or decryption. SSL and TLS protocols support a variety of ciphers
used to authenticate the server and client to each other, transmit certificates,
and establish session keys.

Some ciphers are stronger and more secure than others. Clients and servers
can support different cipher suites. Choose ciphers from the SSL3 and TLS
protocols. During a secure connection, the client and the server agree to
use the strongest cipher they both have enabled for communication, so it is
usually sufficient to enable all ciphers.
